It is important to note that exceeding 1.5C in a single year is not equivalent to breaching the Paris Agreement limit. The goal is generally considered to refer to long-term warming – typically over two or three decades – rather than annual temperatures that include the short-term influence of natural fluctuations in the climate, such as El Niño.

Fucking lmao. So by the time the politicians are ready to say we’ve breached 1.5, we’ll all be dead. Good to know.

typically over two or three decades

So if the average in 2050 is 1.49 (adjusted for natural fluctuations in the climate) - we're all good?

I assume if there's a massive volcanic eruption and the average is 1.7 - they'll [cough] cook the books and say there's no breach because the eruption was a natural fluctuation in the climate.

No, it's just cope. 1.5 is nonesense. No one except China is taking action on global warming and things are so totally out of control we can't build models that predict the rate of acceleration, let alone the outcome.

Asked a Scripps Institute of Oceanography lecturer over 30 years ago why methane from permafrost melting and the ensuing loop was not being factored in to their models, he said "we were focusing on other things". Guess it must have been too hard?

We just launched some satellites in the last couple of years that are capable of detecting methane plumes in the atmosphere. Before then people were just hauling equipment up there to measure the gasses as they were seeping out. It's difficult and imprecise work.

Yeah it's genuinely really hard and the timeframes are not really known

Not that it affects your overall point, but a large volcanic eruption would generally lower the temperature because the ash and chemicals it puts out increase the amount of light reflected back out of the atmosphere instead of being absorbed. It's basically the natural equivalent of the sorts of hairbrained geoengineering schemes techbros like to promise as a miracle cure. AFAIK there have even been what are basically miniature ice ages because of volcanic activity in recorded history.

So if, say, the Yellowstone volcano blew that would drop the global temperature back down for a year or two, as well as decreasing carbon emissions by shutting down the US and its coal mines and oil fields.

Also by shutting down a not insignificant number of kkkonsumers of same

A large volcanic eruption temporarily lowers the temperature, but the contribution of CO2 gas to temperature rise from volcanism would be significant if we weren't speedrunning a return to the Eocene thermal maximum

Still coping. : |

Shit, we are like 4C above fucking 2020 temperatures it feels like the last few years

Capitalism will kill all the billionaires. No matter what. They can't be talked out of it, and if we accomplish nothing, they will make the world unsuitable for life and die slow and horrible when some backup system in their bunkers die and there's no more labor to exploit to fix it, because we're all dead. We know that.

The question is: will you let it kill you first? Will you let them kill you? Will you sacrifice your life for capitalism, or will you risk it on some long-ass odds that someone, somewhere, can still have a future?

Dont tell me. Ask yourself.
